DESCRIPTION
SiP2211 is a dual output low dropout regulator capable of
supplying 150 mA from output 1 and 300 mA from output 2.
The SiP2211 has the outputs independently enabled. Also
the SiP2211 offers a low dropout, low ground current and
extremely low noise with the addition of a bypass capacitor.
Protection features include undervoltage lockout, output
current limit, and thermal shutdown.
The Fixed output version of SiP2211 is available in a lead
(Pb)-free MLP33-10 PowerPAK package and the adjustable
version is available in a lead (Pb)-free MLP44-16 PowerPak
package. Both packages ares specified to operate over the
range of - 40 °C to 85 °C.

b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. Timing is measured from 90 % of LDO #1’s final value to 90 % of LDO #2’s final value.
e. For higher output of the regulator pair.
f. Dropout voltage is defined as the input to output differential voltage at which the output voltage drops 2 % below the output voltage measured
with a 1 V differential, provided that VIN does not drop below 2.25 V. When VOUT(nom) is less than 2.25 V, the output will be in regulation when
2.25 V - VOUT(nom) is greater than the dropout voltage specified.

SiP2211
DETAILED OPERATION
The SiP2211 is a low drop out, low quiescent current
monolithic dual linear regulator, with power-on reset and
open drain driver output features. With output voltage range
from 1.25 V to 5 V the first regulator can source 150 mA and
the second regulator can source 300 mA. The open drain
driver has the capability to drive LED’s for backlighting
applications.
VIN
VIN is the input supply pin for both LDO’s. The bypass
capacitor for this pin is not critical as long as the input supply
has low enough source impedance. For practical circuits, a
1.0 µF or larger ceramic capacitor is recommended. When
the source impedance is not low enough and/or the source is
several inches from the SiP2211, then a larger input bypass
capacitor is needed. When the source impedance, wire and
trace impedance are unknown, it is recommended that an
input bypass capacitor be used of a value that is equal to or
greater than the output capacitor.
VOUT1,2 (LDO Outputs)
The VOUT is the output voltage of the regulator. Connect a
bypass capacitor from VOUTx to ground. The output capacitor
can be any value from 1.0 µF to 10.0 µF. A ceramic capacitor
with X5R or X7R dielectric type is recommended for best
output noise, line transient, and load transient performance.
Enable
The EN1 and EN2 pins control the turning on and off of their
respective regulators in the SiP2211. VOUT of both outputs
are guaranteed to be on when the Enable pin voltage is equal
or greater than 1.8 V. VOUT is guaranteed to be off when the
Enable pin voltage equals or is less than 0.6 V. To
automatically turn on VOUT whenever the Input is applied, tie
the Enable pin to VIN.
Bypass Capacitor
For low noise application and/or increase in power supply
rejection ration (PSRR) connect a high frequency ceramic
capacitor from BP to ground. A 0.01 µF X5R or X7R ceramic
capacitor is recommended.
